Florida winters are mild — but that first cool snap in November still sends plenty of homeowners reaching for the fireplace switch. If yours burns wood, what you put in it matters far more than most people realize.
The wrong firewood creates excess creosote, throws sparks, produces thick smoke, and can turn a relaxing evening into a chimney problem. The right firewood burns hot, clean, and steady. Here is how to tell the difference — with a Florida twist on the usual advice.
Key Takeaways
- Always burn fully seasoned wood — moisture is the primary driver of creosote buildup and poor performance, regardless of species.
- Florida's best firewood choices include live oak, hickory, pecan, and citrus wood — all available locally and well-suited to occasional use.
- Never burn treated lumber, saltwater driftwood, or engineered wood products; the fumes are hazardous and the damage to your chimney is real.
- Store firewood well away from the house and never stockpile it indoors — Florida's warm, humid climate keeps pests active year-round.
- Schedule a chimney inspection before burning season each year, ideally in early fall, to catch creosote buildup and any off-season pest or weather damage.
Seasoned vs. Green Wood: The Rule That Trumps Species
Before you worry about oak versus pine, get this one principle right: always burn seasoned wood. Seasoned simply means the wood has been cut and allowed to dry — typically six months to a year, depending on the species and storage conditions.
Fresh-cut (green) wood still holds a large percentage of its weight in water. When you burn it, a significant portion of the fire's energy goes toward boiling that moisture away rather than producing heat. The result is a cooler, smoldering fire that generates far more smoke and creosote than a properly dried piece of the same species.
Creosote — the tar-like residue that coats your flue — is the real danger here. The CSIA (Chimney Safety Institute of America) recommends a chimney inspection at least once a year, and one of the things an inspector watches for is creosote buildup. At 1/8 inch of buildup, cleaning is warranted; at certain stages, creosote becomes a genuine fire hazard.
In Florida's humidity, seasoning wood properly takes extra attention. Stack it off the ground on a rack, bark-side up, in a spot that gets good airflow and at least partial sun. Cover the top but leave the sides open so moisture can escape. A covered carport or open shed works well. If wood feels heavy, sounds dull when you knock two pieces together, or has bark that is difficult to peel, it is probably not ready.
The Best Firewood Species for Florida Homeowners
Florida's forests and landscaping trees lean toward species you may not see on a Northern firewood guide. Here are the ones worth seeking out.
Live Oak and Water Oak are the gold standard in Florida. Dense, slow-burning hardwoods, they produce a long-lasting coal bed and consistent heat. Because oak is heavy and slow to season, buy it well in advance or source it already seasoned. It is widely available from local tree services, especially after storm cleanup.
Hickory burns similarly to oak — hot, long, and with a pleasant aroma. It is a bit harder to find in South Florida but common in North and Central Florida. Worth seeking out if you want fragrant fireside evenings.
Pecan is an underrated choice for Florida. It seasons relatively quickly compared to other hardwoods, burns clean, and produces a mild, slightly sweet smoke that makes it popular with outdoor grillers too. Pecan trees are common in North Florida, and the firewood shows up at farm stands and feed stores.
Black Locust, while not a Florida native, is sometimes available and is one of the hottest-burning firewoods available anywhere. It splits easily when dry and produces very little smoke.
Citrus wood — orange, grapefruit, lemon — is a genuine Florida gem. Citrus burns with a pleasant, subtle fragrance and produces good heat. It seasons faster than oak. If you have a citrus tree removed or trimmed, ask for the larger limbs. Do not expect this one to be easy to buy commercially, but it is a nice bonus if you have access.
- Live Oak and Water Oak — dense, long-burning, widely available after storms
- Hickory — hot fire, pleasant aroma, more common in North/Central FL
- Pecan — seasons relatively quickly, clean burn, mild fragrance
- Black Locust — very hot, low smoke output
- Citrus wood — fragrant, good heat, faster seasoning than oak
Woods to Use with Caution
Not every wood is bad — but some require more care or have trade-offs worth knowing.
Pine and other softwoods ignite easily, which makes them useful as kindling. However, they burn fast, produce more smoke, and leave behind more creosote residue than hardwoods when burned as a main fuel. A small piece of pine to get a fire going is fine. A whole evening of pine logs is not ideal. If you do use pine, make absolutely sure it is fully seasoned and keep fires hot rather than smoldering.
Eucalyptus is common in Florida landscaping. Seasoned eucalyptus burns reasonably well and produces decent heat, but it contains oils that can spark and pop more than hardwoods. Keep the fireplace screen closed and do not leave it unattended.
Camphor tree wood is abundant in Florida (camphor is actually an invasive species here, so cutting it down is often encouraged). It burns, but the strong aromatic oils create a pungent smoke that many people find irritating indoors. Better for outdoor fire pits than living room fireplaces.
What to Never Burn in Your Fireplace
Some things look burnable but genuinely are not — and putting them in your fireplace creates health risks, chimney damage, or both.
Treated, painted, or stained wood releases toxic fumes when burned. Old lumber, pallets (many are chemically treated), furniture scraps, and plywood all fall into this category. The chemicals used in pressure-treated lumber, in particular, produce hazardous compounds when combusted.
Driftwood from Florida beaches looks appealing around a fire, but saltwater-soaked wood releases corrosive chlorine compounds when burned. Over time this damages the metal components of your chimney system and firebox.
Trash, cardboard, and paper (beyond small amounts used for starting a fire) generate excess ash, unpredictable flames, and — with glossy or coated paper — toxic smoke. Cardboard also tends to send burning embers up the flue.
Wet or green wood, as covered earlier, is not just inefficient — it is a direct contributor to creosote buildup and chimney fires.
Engineered wood products like OSB, particleboard, or MDF contain adhesives and resins that burn dirty and release formaldehyde and other compounds.
- Treated, painted, or stained lumber — toxic fumes
- Saltwater driftwood — corrodes chimney metal components
- Trash, glossy paper, or heavy cardboard — excess ash, toxic smoke, ember risk
- Green or wet wood — creosote buildup, poor heat output
- Engineered wood products (OSB, MDF, particleboard) — chemical off-gassing
A Florida-Specific Note on Storage and Pests
Florida's climate adds a layer of complexity that Northern firewood guides skip entirely. Humidity encourages mold growth in wood piles, and our warm winters mean termites, cockroaches, and other insects stay active year-round. Firewood stacked against the house is an open invitation.
Store firewood at least 20 feet from the house if possible, never against an exterior wall. Bring in only what you plan to burn that evening — do not stockpile logs inside the home. Inspect each piece briefly before bringing it in.
Because Florida fireplace use is light and seasonal — many households burn a fire only a handful of times between November and March — you likely do not need a full cord of wood. A quarter cord or a face cord is often plenty. Buying smaller quantities means you can prioritize quality, fully seasoned wood from a reputable source rather than whatever is stacked outside a gas station in November.
Get the Annual Inspection Before Burning Season
The CSIA recommends an annual chimney inspection regardless of how often you burn. For Florida homeowners, the window before the first cool night — September through October — is the ideal time to schedule one.
A chimney inspection checks for creosote accumulation, blockages (birds and squirrels nest in unused Florida chimneys during summer), cracks in the flue liner, and deterioration of the firebox or damper. Catching a problem before you light that first fire of the season is far safer and less expensive than addressing one after.
Using the right firewood, keeping it properly seasoned, and maintaining your chimney as a system are what keep wood-burning enjoyable and safe in Florida — where a fireplace may only see a few nights of use each year, but still deserves the same respect as one running through a harsh northern winter.
